Definitions

  • the invention relates to a device for locking a container to a vehicle chassis, having a housing, which on the housing side toward the container is provided with a protruding guide block; and having a rotary knob, which is supported in the housing and which has a shaft, guided in the guide block, a hammerhead-shaped locking portion protruding past the guide block, and an actuation portion disposed on the opposite direction from the locking portion, the locking being effected by rotation of the rotary knob about an actuation angle of approximately 90°.
  • Locking devices of this kind are known. They can be rapidly released and secured upon transfer from the ship or railroad car to a vehicle or van carrier. Vehicles designed for transporting containers are therefore equipped with such twist locks. To secure them, the hammerhead-shaped upper part of the rotary knob is introduced into a corner casting that is mounted on all the corners of the container, and the knob is then twisted by 90°. To this end, the corner casting has an oblong slot on its underside, which receives the elongated head of the rotary knob. Shifting the head crosswise locks it and secures it against sliding out. This is the simplest way to secure containers on the transporting vehicle.
  • the rotary knob is additionally provided with a threaded fastening-down or tight-fastening device.
  • the user For locking and securing, the user must first put the rotary knob in the locking position; this requires visual checking and possibly correction of the rotational position. After that, the securing nut must also be tightly screwed.
  • the object of the invention is to improve a locking device of the type referred to at the outset for the sake of easy, fast operability.
  • the invention attains this object in that the guide block has a rotation limiting portion with at least two stops acting in the rotational direction; and that the rotary knob has at least one radially protruding extension, which limits the rotation of the rotary knob in both rotational directions, by contact with the respective stops of the rotation limiting portion, to the rotational range of the actuation angle between a locking position and a release position.
  • Embodying the rotary knob and the guide block according to the invention requires only little additional production cost. If there is a cast housing, then the features according to the invention for the guide block can be cast along with it at the same time.
  • Actuating the device no longer requires visual checking and readjustment, since the respective stop defines the precise locking position and release position, and the user can tell immediately when these positions are attained.
  • the actuation can therefore be accomplished very much faster and more safely.
  • the work involved in transferring the containers can thus be improved perceptibly.
  • the stops are formed by two opposed parallel walls of the rotation limiting portion; and that the extension of the rotary knob has a cross section originating in a square basic shape with rounded corners, and two first rounded features extend opposite one another, spaced apart essentially by the spacing between the parallel walls, over an angular range of approximately 90°, and the remaining second rounded features have a greater spacing from one another.
  • the rotation limiting portion has a rectangular cross section; and that the greater spacing of the second rounded features is substantially equal to the greater width of the rotation limiting portion.
  • a hand lever intended for rotating the rotary knob and pivotably connected to the actuation portion and held in the immediate vicinity of a housing wall, in a position of repose oriented with the axis of the rotary knob, under spring force can be pivoted away from the housing counter to the spring force, in order to assure adequate freedom for the hands upon rotation out of the locking position into the release position or vice versa. Because the hand lever is disposed near the housing, the device becomes very compact, while the pivotability assures convenient use with negligible risk of injury. After use
  • the housing wall closest to the hand lever has at least one protrusion, on which protrusion or protrusions the hand lever can be locked in detent fashion in the locking position and/or the release position, in order to fix the lever against rotation.
  • This security against twisting is attained practically without any additional expense for construction and production, and it protects the locking of the container absolutely securely against unintended loosening.
  • the two detent options may be provided on two separately embodied protrusions or on two sides of a single protrusion that extends over the entire actuation course of the hand lever.
  • the protrusion or protrusions are formed simultaneously with the casting of the housing.
  • Activating or deactivating the twist prevention requires no additional work step.
  • the hand lever In operation of the locking system, the hand lever is already pivoted out of a position of repose counter to the spring force, in order to assure adequate freedom for the hands.
  • the deactivation of the twist prevention occurs automatically, without further action on the part of the user. After rotating it into the locking or the release position, the user simply releases the hand lever. Because of the spring force, the lever then snaps back into its position of repose and in the process entirely automatically activates the twist prevention, by locking in detent fashion behind the protrusion according to the invention from the housing wall.
  • rotary knob is kept axially pressed against the guide block by spring force. Upon motions of the container relative to the housing of the locking device, or if the corner casting is incorrectly placed on the top of the housing, the hammerhead-shaped locking portion of the resiliently retained rotary knob can go along with the motion or accomplish compensation for tolerances.
  • the invention can be still further improved in that the guide block, together with the rotary knob, can be lowered into the interior of the housing, so that the locking portion no longer protrudes from the housing.
  • This provision enables the use of the locking device of the invention in arrangements, known per se, that have lowerable rotary knobs.
  • the guide block is embodied separately and is disposed displaceably relative to the housing.
  • the guide block can be lowered into a lowered position by rotating the hand lever out of the release position counter to the rotational direction intended for the locking.
  • the rotary knob can be moved into the release position by rotating the hand lever by preferably 90° and moved to the lowered position by further rotation, preferably again by 90°, and vice versa.
  • FIG. 1 a side view of a locking device according to the invention in a fixed embodiment, in the release position;
  • FIG. 2 a plan view on the locking device of FIG. 1;
  • FIG. 3 a section taken along the line A--A of FIG. 1 in an enlarged fragmentary view
  • FIG. 4 a side view of a locking device according to the invention in a lowerable version, in the lowered position;
  • FIG. 5 a side view of the locking device of FIG. 4 in the release position
  • FIG. 6, a plan view of the locking device of FIG. 4.
  • the locking device shown in FIG. 1 has a housing 1, which has a protruding guide block 2 on its top side.
  • a rotary knob 3 is rotatably supported in the housing 1.
  • the rotary knob has a shaft 4, which is guided in the guide block 2.
  • the shaft 4 merges with a locking portion 5, which protrudes at the top from the guide block 2.
  • the shaft 4 merges with an actuation portion 6, which protrudes from the bottom of the housing 1.
  • a hand lever 7 is pivotably connected to the actuation portion 6 and is used to turn the rotary knob 3 about its longitudinal axis 8.
  • the hand lever 7 is provided with a bore, in which a compression spring 9 and a ball 10 are disposed.
  • the spring force presses the ball 10 against the actuation portion 6 of the rotary knob 3, and as a result the hand lever 7, in a horizontal position of repose transverse to the vertical longitudinal axis 8 of the rotary knob 3, is kept in contact with a lower housing wall 11 of the housing 1.
  • the hand lever 9 can be pivoted downward away from the housing 1 by approximately 20° counter to spring force, in order upon actuation of the locking device to assure adequate freedom for the hands between the lever handle and the housing wall 11.
  • the hand lever 7 For locking, the hand lever 7 is rotated out of a release position 13, shown in FIG. 2, is rotated by an actuation angle 15 of 90° into a locking position 14. In this process, the locking portion 5 of the rotary knob 3 rotates and with a corner casting 16, indicated in FIG. 5, of a container generates a form lock that firmly connects the container to the vehicle. To release the locking, the hand lever 7 is brought out of the locking position 14 into the release position 13 by rotation in the opposite direction.
  • a protrusion 12 is formed on the housing wall 11, and the hand lever 7, when it is pressed by the spring force into its position of repose, locks in detent fashion in the locking position 14 behind this protrusion.
  • a further protrusion, not shown, from the housing wall 11 is intended for detent locking of the hand lever 7 in the release position 13. In both positions 13, 14, unintentional loosening or locking is practically precluded by the detent locking of the hand lever 7 at the protrusions 12 intended for the purpose.
  • a rotation limiting portion 17 is formed on the guide block 2, as can be seen from FIG. 3; it has two stops 18, acting in one direction of rotation, and two stops 19, acting in the other direction of rotation, and these stops are formed in a simple way by two walls 20, 21 disposed parallel to and opposite one another.
  • the rotary knob 3 has a radially protruding extension 22, whose cross section can be imagined as originating in a square basic shape whose corners are then rounded off.
  • the rounded features 23, 25 merge with a respective one of a total of four straight contact faces, which are intended for contact with the stops 18, 19.
  • a modified guide block 32 is disposed in lowerable fashion together with the rotary knob 3, so that the locking portion 5 no longer protrudes past the top of the housing 31 (FIG. 4).
  • the lowering of the guide block 32 is done by rotating the hand lever 7 out of the release position 13 into a lowered position 34 by a rotational angle 33 of 90°, counter to the direction of rotation intended for the locking.
